I have a problem with my car. When the DPF regeneration is in progress the oil is escapes under the valve-cover.
I replaced the gasket, but it is not working. :-(
One of the injectors different than others. 3x 03G130073T 1x03G130073M
EGR valve cleaned.
In every 1000-1500 kilometers around 700ml coolant disappears from the tank.
